Since the labor and equipment costs are fixed in the maintenance program, the costs that will arise from the loss of capacity of the enterprise can be reduced to a min- imum with the right timing and planning. The capacity loss that will occur during the maintenance can be reduced by pre-planned extra product storage and uninterrupted sup- ply to the customer, and it would be more appropriate to determine the low seasons for the operation and to plan the maintenance more in those periods. In plants that stop pe- riodically and do not operate 24 hours due to energy costs or when there is a decrease in demand, maintenance is of course coincident with the stopping times, preventing pro- duction disruption. 4) FACILITY LAYOUT According to a study, one-third of flour mills in the United States make a small or big change in the machine layouts in their facilities every two years. Since the main criterion taken into consideration in the facility layout is to increase the prof- itability in total production and to ensure ease of operation, improvements can be made in the facility layout over time. Facility layout is another important factor to consider in preventive maintenance management planning. The loca- tion of the facility stands out as a factor that should definite- ly be taken into account in the maintenance management planning in the facilities where the production capacity has been increased by adding equipment, in the facilities where the product type and number are revised according to the market needs, and in cases where the local government re- strictions in which the mill is located and the floor height and dimensions of the mill building are not suitable for comfort- able maintenance. For example, with the addition of an addi- tional machine as a result of the increase in the capacity of a machine whose maintenance is foreseen for a certain period of time, the working area for maintenance is narrowed and the time to be allocated for maintenance increases with the increase in the machines to be maintained. As briefly mentioned above, the most important element in maintenance management in mills is pre-planning. Effi- ciency in production, which is the real purpose of mainte- nance, can be achieved when the four topics mentioned above are planned realistically in a coordinated manner. Otherwise, the success of the planned maintenance is left to chance, which increases the risk of failure during the operation of the enterprise and the enterprise may face unexpected costs. We, as Selis company, are fully aware of the importance of maintenance management in mills in today's conditions, both in the design of our machines and in our complete plant projects, and we provide full support to our customers in mill maintenance by designing equipment that is easy and fast to maintain, and by designing the project of the plant in a way that provides the easiest maintenance. For example, with the central lubrication system we apply in our roller mills, we can lubricate safely from a single point without the need to stop the roller mills, even the points that are difficult to reach, with the central lubrication system, easily and quickly. Like- wise, thanks to our patented systems, we can disassemble the process of replacing worn rolls in roller stands in a very short time, like 15 minutes, and replace them with new roller mill rolls as a package. This process, which would normally take at least half a day for a roller mill, can be completed in as short as 15 minutes, thus providing a serious maintenance advantage for the mill. On the other hand, by taking the electronic control panel from the side covers to the middle of the roller mills, the cable crowd in the section where the pulleys are located on the sides of the machine is reduced and maintenance is facilitated. All similar maintenance ad- vantages in our other machines can be obtained by visiting our website or by contacting our company directly.
